Where did you get the idea from that spending long stretches of time with a small human wouldn’t be mind numbingly dull?
Pretty much everywhere, you look, right? There’s a serious amount of fakery online, on tv, even amongst our friends unless you look a bit closer. I think it’s really important to recognise this. We can see through ordinary advertising and know that we’re being manipulated to buy the beer/make up/ pizza that will make us happy. It’s harder to see the insidious and ubiquitous messaging about parenting. People can make a lot of money presenting a facade and our perception of reality is being altered.
Once I realised that parenting is relentless, time dragging drudgery in the main, I was better able to experience the good bits. And once I started giving myself credit for doing the basics well (feeding, clothing, cleaning, cuddling) instead of wallowing in mum guilt and comparisons, it freed up more mental energy for finding the parts of parenting that I excelled at, and the points of connection (these can be different for different children so don’t worry too much ) and enjoyment.
The stage of being constantly instructed and criticised for playing wrong does pass (that was tiresome!) you can be playful with that, push back a little, stretch him to use his language skills by being a little dense, and any of those reactions take you out of yourself a bit.
And sometimes it’s actually better to say no to activities you truly loathe (“mum doesn’t play football”) and keep a firm boundary rather than giving off confusing emotional signals where you’re pretending and the dc doesn’t quite know what’s off.
Don’t feel you always have to be child centric. It’s good to get dc to join in with adult tasks and activities too, or to go for a walk with you first before doing something of their choosing. Obviously if there are sensory issues you might need to mitigate that.
I used to plan my day in 15 minute segments, and if I got 30 minutes out of the activity it felt like a lottery win. Tidying up is a legitimate activity with small children. The trick is to keep a low calm energy about it (don’t gamify it, make it a race or put on hyper music regardless of the advice you’ll read on every parenting blog ever. That leads straight to trouble)
Hang in there. It really does get better.
